18QHTF21-85.761-PD

Overview

The 18QHTF21-85.761-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 85.761 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component features an Enable/Disable control interface and supports Standby (Power Down) modes for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports standby mode for power reduction
• Compact surface-mount package design
• LVCMOS output compatibility

Applications

• Embedded systems requiring precise timing
• Portable electronic devices
• Communication modules

Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct functionality. Confirm that the PD suffix aligns with the required standby capabilities and that the 1.8V supply voltage matches the target circuit design before procurement.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. Ensure the application can accommodate the 4-SMD footprint and that the LVCMOS signal levels are compatible with the connected digital logic interfaces.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-power oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package, catering to space-constrained consumer and industrial electronics applications.

Replacement Considerations

Direct substitutes must match the 85.761 MHz frequency, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications with alternative manufacturers to ensure functional equivalence.
